convert UTF 8 string to URL (ajax)

Question

I have a string for example, that may contain special characters (+,=,&, etc...):

"Írja ide kérdését, majd üssön entert!"

and I would like to convert it to URL accepteble string for XHR like (because IE does not do it automatically):

"%C3%8Drja%20ide%20k%C3%A9rd%C3%A9s%C3%A9t,%20majd%20%C3%BCss%C3%B6n%20entert!"

Is there any javascript function for this?

Thank you!

You should use the encodeURI function:

encodeURI("Írja ide kérdését, majd üssön entert!");
// => "%C3%8Drja%20ide%20k%C3%A9rd%C3%A9s%C3%A9t,%20majd%20%C3%BCss%C3%B6n%20entert!"

after receiving is there any conversion required? (in PHP) – Sep 14 '11 at 12:40
I'm asking it because the + sign does not appear at all after getting data. – Sep 14 '11 at 12:41
Server-side, you may want to look at the `urldecode` PHP function http://php.net/manual/en/function.urldecode.php – Arnaud Leymet Sep 14 '11 at 12:42
I have tested and encodeURI does not cover + singn. (but this works: encodeURI(msg).replace("+","%2B")); ) – Sep 14 '11 at 12:54
Check my other answer, that takes your "+" request into account – Arnaud Leymet Sep 14 '11 at 12:58

You have added a + sign.

To encode this plus sign too, use the encodeURIComponent function:

encodeURIComponent("+Írja ide kérdését, majd üssön entert!");
// => "%2B%C3%8Drja%20ide%20k%C3%A9rd%C3%A9s%C3%A9t%2C%20majd%20%C3%BCss%C3%B6n%20entert!"

Check this thread for more informations about the differences between escape, encodeURI and encodeURIComponent functions.
